Abstract

A data broadcasting station (2) transmits a multiplexed signal in which multimedia data encoded in a prescribed coding system are at least multiplexed in a broadcasting form. A file manager (14) stores the multimedia data received by a tuner (11) and decoded by a decoder (12) in a storage device (15) while creating management information therefor and registering it in a table (13). A browser (16) requests of the file manager (14) multimedia data to be referred to, and lets it displayed on a monitor. The file manager (14) increments/decrements a retention coefficient on the basis of a frequency of reference to the multimedia, and determines whether or not to delete each multimedia data stored in the storage device (15). Thus provided is a terminal device which can effectively utilize the capacity of the storage device (15) without deleting multimedia data frequently referred to by the user.
